HELIOS illuminates autonomous robotics
Researchers in Singapore have developed HELIOS, a stretchable, self-healing and illuminating material for a range of uses including robotic smart farming, space exploration and search and rescue missions.
The new stretchable material, when used in light-emitting capacitor devices, is claimed to enable highly visible illumination at much lower operating voltages and is also resilient to damage due to its self-healing properties.

This innovation, called the HELIOS (Healable, Low-field Illuminating Optoelectronic Stretchable) device, was achieved by Assistant Professor Benjamin Tee and his team from the National University of Singapore (NUS)’s Institute for Health Innovation & Technology and the Department of Materials Science and Engineering at the NUS Faculty of Engineering. The results have been reported in Nature Materials.
“Conventional stretchable optoelectronic materials require high voltage and high frequencies to achieve visible brightness, which limit portability and operating lifetimes. Such materials are also difficult to apply safely and quietly on human-machine interfaces,” Asst Prof Tee said in a statement.
